Embodiment Construction

[0012] The present invention will be described in detail below with a single-effect heat pump / double-effect refrigerating unit and system in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the steam turbine 2 of the power plant draws steam and enters the high-pressure generator 11 of the integrated unit 8 as the driving energy for heating or cooling of the unit. During heating in winter, the unit operates in single-effect heat pump mode, such as figure 2 , that is, part of the cooling water of the power plant is used as a waste heat source to connect to the evaporator 14 of the integrated unit, the unit valves F14 and F16 are closed, and the valves F13 and F15 are opened. External heating, at this time figure 1 Valves F1, F2, F5, and F6 in the center are opened, and valves F3, F4, F7, and F8 are closed; during cooling in summer, the unit operates in double-effect cooling mode, such as image 3 , that is, part of the cooling water of the powe...

Abstract

The present invention provides a single-effect heat pump / double-effect cooling absorption set and a combined heat, electricity and cold supply system, and belongs to the field of afterheat utilizing and refrigerating technology. The integrated single-effect heat pump / double-effect cooling absorption set is mounted in a thermal power plant, and the exhaust of the steam turbine is connected to the high pressure generator of the integrated set and used as the driving energy for heating and refrigerating. The integrated single-effect heat pump / double-effect cooling absorption set operates either in single-effect heat pump mode for heating in winter or in double-effect cooling mode for refrigerating in summer. The present invention has the comprehensive advantages of saving in energy, low power consumption, being environment friendly, etc.

Description

Technical field: [0001] The invention belongs to the technical field of waste heat utilization and refrigeration in thermal energy and power engineering. Background technique: [0002] Cogeneration of heat, electricity and cooling is a relatively reasonable way of energy consumption. Among them, the use of steam extraction from steam turbines to generate high-temperature water through heat exchangers for heating and centralized heating in winter, and the use of steam extraction to drive absorption refrigerators for cooling in summer are The most common technical solution. In winter heating and central heating, in order to carry out long-distance transportation, it is necessary to use higher parameters of steam extraction to heat the heating circulating water; in order to reduce the pipe diameter of the heating circulating water, the supply and return water of the heating circulating water The temperature difference is large, and energy-saving means can be used in it. In su...
